David Olusoga's A Black History of Britain is a rich and revealing exploration of the extraordinarily long relationship between the British Isles and the people of Africa. Drawing on new genetic and genealogical research, original records, expert testimony and contemporary interviews, A Black History of Britain reaches back to Roman Britain, the medieval imagination and Shakespeare's Othello. Unflinching, confronting taboos and revealing hitherto unknown scandals, Olusoga describes how black and white Britons have been intimately entwined for centuries.
